I bought it with the refilable cartrige to save money but turns out this is better than every other DI I've used! In the past I've used cartrigest from coralife and the package deal cartrige from the "another" popular website. I NEVER had 0 tdi, though maybe my meter was off. Now I read 0 even with my old (2+ years) ro membrane. I think the secret is that it's sealed so well and also that you pack it real nice yourself (and that packing later doesn't get messed up with shipping). Only suggestion is that they should provide replacement bottom foam with the resien, my foam seemed to get a bit mangled when screwing the bottom on..

I was buying the premade kent cartridges until I started using the bulk DI resin. I save a ton and get close to 7 refills which can add up quickly when buy the premade one. I have well water and my TDS always comes out at 0, this stuff is the best.

Works well, keeps my TDS at 0 until exhausted.

I've done quite a few hundred gallons since purchasing this stuff and I'd have to say that it's holding up much better than the "manufacturer" brand. Color is just fine whereas the other stuff would have started to change on me already. Not sure what to think other than it's higher quality.

Good Stuff but...By Davidon 10/8/2011

Good stuff but I am going to save the little bit of money because I use a TDS meter and I don't need the color change. I found that by reading TDS the resin works well past the time it changes color.

Saves you money and very easy to doBy Sarahon 9/17/2011

I got tired of spending so much for DI resin cartridges that I thought I would give this a try. It was so easy to do that I wondered if I did it right. I am happy to say that I did do it right and my ro unit does not know the difference. My output reads zero tds! I will be back for more when I need it.

So nice to use.By Ryanon 9/5/2011

This resin is great, the color change is drastic by comparison to other color-changing resins on the market. I will continue to use it.

This product works well. When exhausted it changed colors from blue to brown. TDS went to 0. This is a very good and affordable product.

I used to buy the cheapest resin I could find, and only knew when you change it by testing TDS or by the smell of the water. We have really bad water so occasionally it would go south before I could tell and I would get nuisance algae outbreaks. The color change beads make it easy to tell how much time I have left. Started changing right away from the bottom up, so I feel much more confident about my RODI quality.

After trying some DI resin off of ebay this was a huge improvement. I was getting 30 TDS from the ebay resin and after switching to this I've been at 0 TDS for months

I can refill my canisters 6 times and save $20.00 each canister, that's $120.00 less then retail

Great Quality & Easy By Christopheron 8/5/2011

Once you refill your DI cartridge one time it is not difficult at all.
DI resin does have a shelf life so don't buy bulk unless you need it within a few months.

I purchased this to replace the DI resin in my Vertex RO/DI unit. It works very well but doesnt last as long as the original product that came with the unit. Still a very good deal considering the price diffrences. I may have to replace the DI resin often but Ill be saving $$$$ in the long run.

This material has got a nice color indicator that's easy to figure out. Why not save some money on packing it yourself. It takes very little effort.

We have extremely hard water where I live with fluctuating tap TDS that ranges from 330's and spikes to nearly 600! Regardless of the source water, since I have changed to a dual DI canister system - my final TDS is always 0. Unbelievable!!!

I have low TDS to start, but my post RO water is around 9TDS and this gets it to 0 most of the time.

I have tried other resin bulk reef's is the best, the color change is very helpful and the price is great, my local fish store tried selling me the regular resin for 28 bucks.

I really like that I'm able at a glance see the color change intheDi that it will need to be changed. I have a TDS monitor on the system, but have learned no need to keep checking it until the color is close to being gone. I'm completely happen with the product.

It's nice to have this color changing resin, but it usually changes long before it's exhausted. I still use a TDS meter to maximize the use and only change it when I see a 1ppm reading.

Blue-my favorite color By Jeffrey-resin eateron 7/6/2011

Great stuff-you can cram it into your container of choice, then pound it on the table, and it doesn't even cry. Now that's selective breeding at it's best. (LOL)
Then, when you're finished using it, you can pure it onto the floor, and lean your head back and dream that you are at the beach while you wiggle your toes in it.
Ahhhh, Bulk Reef Supply..... your da man!!!!!!
